Phosphatidylinositol 4,5-Diphosphate 30-34 ATP binding cassette subfamily C member 8 Homo sapiens 166-170 28092267-5 2017 Intricate interactions between TMD0, the loop following TMD0, and Kir6.2 near the proposed PIP2 binding site, and where ATP density is observed, suggest SUR1 may contribute to ATP and PIP2 binding to enhance Kir6.2 sensitivity to both. Phosphatidylinositol 4,5-Diphosphate 91-95 ATP binding cassette subfamily C member 8 Homo sapiens 153-157 28086082-6 2017 In another structural population, a putative co-purified phosphatidylinositol 4,5-bisphosphate (PIP2) molecule uncouples Kir6.2 from glibenclamide-bound SUR1. Phosphatidylinositol 4,5-Diphosphate 57-94 ATP binding cassette subfamily C member 8 Homo sapiens 153-157 28086082-6 2017 In another structural population, a putative co-purified phosphatidylinositol 4,5-bisphosphate (PIP2) molecule uncouples Kir6.2 from glibenclamide-bound SUR1. Phosphatidylinositol 4,5-Diphosphate 96-100 ATP binding cassette subfamily C member 8 Homo sapiens 153-157 24429282-3 2014 PIP2 also modifies Syn-1A clustering in plasma membrane (PM) that may alter Syn-1A actions on PM proteins like SUR1. Phosphatidylinositol 4,5-Diphosphate 0-4 ATP binding cassette subfamily C member 8 Homo sapiens 111-115 24429282-4 2014 Here, we assessed whether the actions of PIP2 on activating KATP channels is contributed by sequestering Syn-1A from binding SUR1. Phosphatidylinositol 4,5-Diphosphate 41-45 ATP binding cassette subfamily C member 8 Homo sapiens 125-129 24429282-5 2014 In vitro binding showed that PIP2 dose-dependently disrupted Syn-1A SUR1 complexes, corroborated by an in vivo Forster resonance energy transfer assay showing disruption of SUR1(-EGFP)/Syn-1A(-mCherry) interaction along with increased Syn-1A cluster formation. Phosphatidylinositol 4,5-Diphosphate 29-33 ATP binding cassette subfamily C member 8 Homo sapiens 68-72 24429282-8 2014 First, we showed that PIP2-insensitive Syn-1A-5RK/A mutant complex with SUR1 could not be disrupted by PIP2, consequently reducing PIP2 activation of KATP channels. Phosphatidylinositol 4,5-Diphosphate 22-26 ATP binding cassette subfamily C member 8 Homo sapiens 72-76 24429282-9 2014 Next, Syn-1A SUR1 complex modulation of KATP channels could be observed at a physiologically low PIP2 concentration that did not disrupt the Syn-1A SUR1 complex, compared with higher PIP2 concentrations acting directly on Kir6.2. Phosphatidylinositol 4,5-Diphosphate 97-101 ATP binding cassette subfamily C member 8 Homo sapiens 13-17 28092267-5 2017 Intricate interactions between TMD0, the loop following TMD0, and Kir6.2 near the proposed PIP2 binding site, and where ATP density is observed, suggest SUR1 may contribute to ATP and PIP2 binding to enhance Kir6.2 sensitivity to both. Phosphatidylinositol 4,5-Diphosphate 184-188 ATP binding cassette subfamily C member 8 Homo sapiens 153-157 24429282-12 2014 These results taken together indicate that PIP2 affects islet beta-cell KATP channels not only by its actions on Kir6.2 but also by sequestering Syn-1A to modulate Syn-1A availability and its interactions with SUR1 on PM. Phosphatidylinositol 4,5-Diphosphate 43-47 ATP binding cassette subfamily C member 8 Homo sapiens 210-214 21654216-0 2011 ATP activates ATP-sensitive potassium channels composed of mutant sulfonylurea receptor 1 and Kir6.2 with diminished PIP2 sensitivity. Phosphatidylinositol 4,5-Diphosphate 117-121 ATP binding cassette subfamily C member 8 Homo sapiens 66-89 21321069-0 2011 N-terminal transmembrane domain of SUR1 controls gating of Kir6.2 by modulating channel sensitivity to PIP2. Phosphatidylinositol 4,5-Diphosphate 103-107 ATP binding cassette subfamily C member 8 Homo sapiens 35-39 16373383-1 2006 ATP-sensitive K+ channels composed of the pore-forming protein Kir6.2 and the sulphonylurea receptor SUR1 are inhibited by ATP and activated by Phosphatidylinositol Bisphosphate (PIP2). Phosphatidylinositol 4,5-Diphosphate 179-183 ATP binding cassette subfamily C member 8 Homo sapiens 101-105 16373383-3 2006 Regulation of Kir6.2 by SUR1, however, is not well-understood, even though this process is ATP and PIP2 dependent. Phosphatidylinositol 4,5-Diphosphate 99-103 ATP binding cassette subfamily C member 8 Homo sapiens 24-28 16373383-8 2006 Based on macroscopic and single-channel data, we propose a model in which entry into the high-P(o) bursting state by the C166A mutation or by SUR1 depends on the interaction of PIP2 with R176 and R177 and, to a lesser extent, R54. Phosphatidylinositol 4,5-Diphosphate 177-181 ATP binding cassette subfamily C member 8 Homo sapiens 142-146 10435998-3 1999 Phosphatidylinositol 4, 5-bisphosphate (PIP(2)) profoundly antagonized ATP inhibition of K(ATP) channels expressed from cloned Kir6.2+SUR1 subunits, but also abolished high affinity tolbutamide sensitivity. Phosphatidylinositol 4,5-Diphosphate 0-38 ATP binding cassette subfamily C member 8 Homo sapiens 134-138 9804555-3 1998 It is reported here that phosphatidylinositol-4, 5-bisphosphate (PIP2) and phosphatidylinositol-4-phosphate (PIP) controlled ATP inhibition of cloned KATP channels (Kir6.2 and SUR1). Phosphatidylinositol 4,5-Diphosphate 25-63 ATP binding cassette subfamily C member 8 Homo sapiens 176-180 9804555-3 1998 It is reported here that phosphatidylinositol-4, 5-bisphosphate (PIP2) and phosphatidylinositol-4-phosphate (PIP) controlled ATP inhibition of cloned KATP channels (Kir6.2 and SUR1).
